Unable to apply for an ADSL line

Hi. I have been having endless issues with Telkom to have my line upgraded so I can have ADSL connected. As a new customer, I had a prepaid Telkom line. I was told I need yo convert this to a fixed line in order to have ADSL. Now that the upgrade has been finalised, I have called 3 times to the called centre and was told each occasion, a reason whey they cannot upgrade me. First it was the wrong option I selected, and they can't transfer me to the correct department. Second was they cud not upgrade me as I need to wait 24 hours. Third call was, they can't upgrade me as there is no ports available. Btw, each call last more than 30 mins, due to holding on for someone to answer. When speaking to the technician, who help with the fixed line upgrade, he says there is many ports available and can set me up but cannot as he needs the sales order first. I have spent more than 1.5 hours on the phone and no resolution. As a new client, this is poor service received and this is to take on a new product, installing internet at my home. Who do I need to speak to have this sorted out??? I have received one answer from the sales department and another from the technician.
